Краткий ответ. В заданиях 6–7 нужно рассказать, где находились предметы в классе утром и днём. Вот готовый образец:
Morning
- In the morning, the classroom was tidy.
- The fan was on the bookcase next to the wall.
- The blackboard was clean.
- The chairs were under the desks.
- There were four desks in front of the teacher's desk.
- The bin was next to the cupboard.
Afternoon
- In the afternoon, the classroom was messy.
- The fan was on the floor in front of the teacher's desk.
- There were drawings on the blackboard.
- The chairs were upside down.
- There were books and papers on the floor.
- The teacher's desk was in front of the blackboard.
Принцип. Здесь описывается, как было раньше, поэтому используется Past Simple:
- was — если предмет один: The fan was... The blackboard was...
- were — если предметов несколько: The chairs were... There were books...
- После глагола ставим предлог места: on, under, next to, in front of, behind, between, in.
- Конструкция There was / There were нужна, когда говорим «был / были»: There was a bin... There were four desks...
Проверка. The fan — единственное число, значит was. The chairs, books, desks — множественное число, значит were. Сравни: утром вентилятор был на шкафу, а днём — на полу перед столом учителя. В учебнике дан именно такой образец.
